Spring Cloud Sleuth Benchmarks

This module can run benchmarks using the following tools

  • JMH

  • JMeter

How to run it?

In the root folder inside the scripts folder there are the following benchmark scripts:

  • runJmhBenchmark.sh

  • runJmeterBenchmarks.sh

Just execute them from the root folder like this:

./scripts/runJmeterBenchmarks.sh
./scripts/runJmhBenchmarks.sh

How do they work?

For JMH we’re building a shaded JAR file that is next executed.

For JMeter we’re running two applications, one with Sleuth, one without with Spring Boot Maven Plugin. Next a Maven JMeter plugin is executed that loads the *.jmx files, starts JMeter and prints out the results. At the end Spring Boot Maven Plugin stops the applications.

What are we testing?

For now we’re testing the performance impact of the following:

  • our custom Trace HTTP filter

  • instrumentation of controllers - @Callable returning and the sync one

  • instrumentation of RestTemplate

  • @Async annotated methods
